CHARLES K. STINSON, OF

NEW YORK, N. Y., ASSIGNOR TO THE AMERICAN MACHINE FOR MAKINGCARPET-LININGS.

SPECIFICATION forming part of Letters Patent No. 240,198, dated April12, 1881. Application filed January 25, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES K. STINsoN, a citizen of the'Uuited States,residing in the city, county, and State of New York, have inventedcertain Improvements in Machines for Making Carpet-Linings, of which thefollowing is a specification.

This invention relates, in the main, to a machine for manufacturingcarpet-linings made to up of sections which are connected together bymeans of strips of paper and cords pasted thereto, all as will be fullyhereinafter setforth. In the drawings, which serve to illustrate myinvention, Figure 1 is a side elevation of 1 the main portion of themachine, the portion designed for constructing the sections being shownin front elevation. Fig. 2 is a plan of the entire machine. Fig. 3 is aside elevation of that portion of the machine designed for 2constructing the sections. Fig. 4 isa view showing the lining as made inmy machine. Figs. 5, 6, 7, and 8 are detached detail views, on a largerscale, designed to illustrate the more intricate portions of themechanism. 2 5 Referring to Fig. 4, I will first describe the liningwhich is made by my machine.

Sections A A are made by covering a strip or lap of cotton, wool, orsimilar fibrous material with stout paper, and pasting down the 0overlapping edge of the paper upon that underneath it. These sectionsare made of a length corresponding to the intended width of the lining,and are connected by means of binding-strips B B, of strong paper,turned or hemmed over the ends of the sections, and another strip orstrips, 0, arranged as intermediates between the borders. There may beone,

two, or more of these latter, depending on the width of the lining. Ialso lay within the fold of the marginal binding-strips B, or undertheir folded edges, a continuous cord, a, and

also lay similar cords, when necessary, between one or all of the strips0 and the sections.

These cords give the lining all the strength required. In thedescription of my machine,

which follows, I have described the mechanism employed for laying thesecords.

I will now describe my machine for making the lining, and for the sakeof clearness will refer to that portion of the machine which constructsthe sections as the section-machine,

and that portion which connects the sections and completes the lining asthe main machine.

Referring to Figs.2and3,which illustrate the section-machine, D is aroll of paper mounted in bearings in a suitable frame. This paper servesas covers for the cotton laps, and the two together form the section.The paper passes from the roll under a slitting-wheel, E, which bears ona roller, E, below it. The wheel E slits the paper in the'center, andthe two strips pass to pasting-wheels F, which are fed by doctor-rollsG, arranged to rotate in paste-vessels H in the usual way. The paste isapplied to but one edge of each strip, an idler-roll, I, being employedto keep the strips down to the paste-wheels and to the bearingrolls I,between said paste-wheels, on the same shaft. At this point the cottonlaps J, one for each strip of paper, are received from the scratcher, socalled. [t will notbe necessary to describe this machine for forming thecotton -laps, as it has long been in common use. I will merely say thatthe laps are, or may be, brought from the scratcher along ways oraprons, or up inclined planes J, as shown, and they then pass betweenthe idler I and the bearing-rolls I, under the strips, as indicated bythe dotted lines in Fig. 2. The strips and laps pass now to folders K,which are made from sheet metal and adapted to turn the edges of thestrips over on the laps, so as to completely inclose the latter. Thepasted edge of the strip is thus brought down upon the pa- 8 per beneathit, and the section-strip so formed passes immediately under the cuttingand compressing roll L. This roll is of such size that its circumferenceequals the length of the section, and it is provided with acutting-blade, 99 I), set in or secured to its periphery, which bladeserves to cut off the sections from the strip at every revolution of theroll. Below the roll I is a bearing-roll,M, covered, by preference, withcopper or other material suitable 9 5 to cut on. The sections, astheyare cut off, fall upon an endless apron, N, which travels at rightangles to the movement of the section-strip, and which forms a part ofthe main machine, which I will now describe.

Referring to Figs. 1 and 2, O is the main frame of the machine, and. Pisa steam-heated drum or cylinder arranged to revolve in bearings in thesame.

Q, is the steam-pipe which leads steam to the drum at the trunnions orjournals in the usual way,andRis themaindriving-shaft,which communicatesrotary motion to the drum through gears c c and a toothed rim, (7, fixedto the drum, as shown.

S is an endless apron, which passes around the drum p and sundrybearing-rolls, (1 (1 850., as shown. The roll d is mounted in bearingsat the ends of arms 0 a, hinged to the main frame, and connected bystruts or links 6 c with adjustable slotted sliding-plates 0 By means ofthis device the endless apron S may be strained taut and caused to presstightly up to the drum. The construction of the apron S will behereinafter referred to more particularly.

T T represent the several rolls of paper for forming the connecting andbinding strips. These rolls are mounted in suitable bearings at the backof the machine, and the strips are led therefrom over a guide-roll, f,thence over paste wheels or rolls g g, (which latter are fed bydoctor-rolls h h, arranged to rotate in paste troughs or vessels t' i,)thence around weighted bearing-rolls j j, and thence up to the bed ofthe machine, where they pass onto an endless apron, U, arranged totravel toward the drum 1? and bear the pasted strips thereto.

Returning again to the mechanism at the rear end of the machine, 7c aretwine-spools,which supply the cords (6 a. (Shown in Fig. 4:.) The cordsfrom these spools are led first from suitable-or ordinary tensiondevices, and thence around the wheels in the paste-troughs, over thebearing-rolls and the strips B 0, up to the endless apron U. The cordsand strips are joined together by this operation and travel together. Asthe strips B O and the cords a are borne forward they pass under themouth of the hopper V, into which the sections drop from the endlessapron N.

The hopper V and its attendant mechanism will require particulardescription, and attention is called to Figs. 6 and 7 for a betterunderstanding of the same. It will be first observed that the opening inthe bottom of the hopper corresponds in size and shape with one of thesections, and that it is arranged with reference to the strips B O,which pass under it, the bottom of the hopper being raised above thesaid strips a distance equal to the thickness of a section, A, or atrifle in excess of this. Fig. 7 is a section taken through the hopperand the rolls connected with it, as well as a few of the sections A inthe hopper and a portion of the lining as it is being made. The hopperstands inclined, so that the sections, as they fall into it from theapron N, overlap each other at the back, as clearly shown. Just in frontof the hopper are arranged two rolls, 1 l, and just below the rear edgeof the delivery-openin g of the hopper is arranged a feed-roll, m,provided with pushing blades or points it, which, as the roll revolves,strike and push forward the lower section from the hopper until it iscaught between the rolls 1 Z. As this section is carried forward out ofthe way the next section drops down, and the operation is repeated. Abearing-roll, m, rests upon the roll at and keeps the strips B O, (withthe attached cords a,) which pass between the rolls 1 l and m m, presseddown snugly to the feed-roll. The roll 1 is also a bearing-roll.

Referring to Fig. 6, (which is a plan arranged to illustrate the mode ofturning over the binding-strips 13,) W W are sheet-metal turning orbinding plates, arranged, by preference, oppo site to and in front ofthe hopper, at its side, so as to begin turning the strips B at a pointopposite to or back of the hopper, and to complete the turning in frontof the hopper. The binding might, however, be accomplished altogetherinfront of the hopper. The roll I is somewhat shorter than the sections,as shown, so as not to interfere with the binder, and the roll m may bea series of short rolls or wheels on a common shaft, the said rollsbeing arranged to avoid the blades or points a in the feed-wheel in awell-known way. As the lining passes out of the bindersW it issubstantially completed; but it passes under the roll at to the drum P,where it is compressed between said drum and its encircling apron S. Asit passes around the drum it is thoroughly dried and pressed, and passesthence out and over the roll d complete and ready for folding.

The folding-machine is illustrated in Figs. 1 and 8. It is arrangedunder the frame of the machine, and receives the finished liningfrointhe drum, as shown in Fig.1. The folder consists of a sort of box, inwhich the lining is folded back and forth by means of a reciprocatingarm bearing a finger, which engages the bight of the incoming strip oflining and carries it across from side to side of the box, it beingreleased at the end of each movement by means of a cam which throws itback.

Let 11 represent the sides of the box, and 2 2 vertically-slotted platesarranged between the ends of the same. I have shown but one end of thefolder; but it will be understood that both ends are provided with likemechanism. A block, 3, slides in the slot in plate 2, and from saidblock projects a bearing-stud, 4, on which oscillates a boss, 5, towhich is fixed a crank, 6, and to which is hinged the folding-arms 7. Aspring, 8, behind the folding-arm keeps it pressed up to a cam-plate, 9,secured also to the stud 4. The arm 7 has a finger, 10, which takes intothe bight of the lining strip and carries it from side to side. Theoscillation or reciprocation of the foldingarin may be produced in anyway; but I have shown it as produced through the medium of aconnecting-rod, 11, which extends from the crank 6 to a shorter crank,12, on the projecting shaft of the roll d.

So far as described, the operation is as follows The continuous strip oflining is fed into.

the folding-box over a guide-roll, 13, and the finger 10 engages thebight, when the folding ICO has beenstarted, and carries it over to theside of the box. As the arm reaches the end of its stroke it rides onthe higher part of the cam 9, (see 14 14 in Fig. 8,) which draws thefinger 10 back clear of the edge of the lining-strip and allows it topass back in its return-stroke over the top and into the next big-ht.The block 3 rises as the box fills, sliding up in the slot and, bearingwith it the cams and other parts connected with it. To counterbalancethese parts I employ a weight or weights, 15, connected, in somesuitable manner, with the parts to be counterbalanced by means of cordsor chains, substantially as set forth.

To hold the last lap or'fold down while the next is being made, and toprevent the return movement of the finger 10 from disarranging it, Iemploy a device shown in the right and left in Fig.8. Between the cam 9and the folding-arm 7 I pivot on the cam-boss a forked holder, 16. Thebranches of this bolder pass upward and outward, and have fingers 17 attheir extremities, which take into the bight of the folds next to thesides of the box. Being pivoted, however, when one end swings in andinserts its finger into the fold the other end swings out. This holderis operated by the folding-arm as it plays to and fro. \/Vheu the arm 7swings over to one side its butt, below the hinge, first comes incontact with a branch of the holder on that side and presses it in. Theupper part of the arm then strikes the higher part of the cam and isthrown back. Then, when the arm swings to the other side, the engagedfinger of the holder remains inserted and permits the folder-finger tolay the next fold; but on the folder reaching the termination of itsstroke on that side the other branch of the holder is pressed in and theopposite one released.

I construct the endless apron S, and also the aprons N and U, wheredesirable or necessary, of metal slats or plates mounted on Vaucausonchains. This construction is shown in Fig. 5, the upper view being aplan. In this figure a represents the slats, and b the links of thechain. The links may be secured to the slats by means of screws orrivets. Such an apron will not warp, stretch, or get out of shape fromthe contact with the hot drum, and is always positive in its action. I

The bearing-rolls d (1 &c., may be simply narrow rolls or wheels fixedat intervals on a common shaft.

The section-machine is shown as constructed to make but twosection-strips at one time; but by making it wider any number may bemade, or only one may be made and the slitting-wheel omitted. I havealso shown the machine as constructed to make a narrow strip of liningwith but one intermediate strip, 0; but it may be constructed to makestrips of any desired width.

In lieu of the slotted adjusting-plates 0 e ratchets or other knownadjusting devices may be employed.

It will be understood that the various parts of the machine must work inunison, and suitable wheels, belts, &c., maybe employed for driving thevarious wheels, rolls, aprons, &c. This, however, requires only ordinarymechanical skill, and I do not deem it necessary to describe them here.I will say, however, that the section-machine may be driven from thescrateher to good advantage, if desired.

The cutting-roll L may, if desired, have a circumference equal in extentto the length of a section, or equal to any multiple thereof.

I prefer to drive such of the rolls, pastewheels, cutters, feeders, &c.,as are notdesignated as bearing-rolls or idlers, either directly orindirectly, through belts, chains, or gearwheels. Itis importantthatthey should have a positive motion, and that too much strain should notbe thrown upon the strips of paper employed.

In lieu of the feed-roll 122, provided with points or blades 12, I mightemploy a reciprocating feeder or pusher; but I prefer the roll shown.

As before stated, I do not claim a carpet-lining made up of sections inthis manner, nor do lclaim, broadly, that pasting and folding wrappersor strips in this manner by means of paste-wheels and folders is newwith me.

I am also aware that steam-heated drums, rotating in contact withaprons, is common in paper-making and other machinery; but

What I do claim is- 1. The section-machine comprising bearing or gripingrolls to receive the strips of paper and the lap from the scratcher,pasting-rolls to apply paste to the edge ofthe strip, a folder to foldthe paper over the lap, and a compressing and cutting rollto cut thesections from the section-strip of the proper length, all combined andarranged substantially as set forth.

2. The combination, to form a machine for constructing the sections fora carpet-lining, of a slitting wheel or wheels to divide the paper as itcomes from the roll into strips of suitable width, bearing or gripingrolls to receive the strips of paper and the laps and carry them forwardin proper conjunction, pastingrolls to apply paste to the edges of thestrips, folders to fold the strips over the laps so as to envelope them,and a compressing and cutting roll to cut the sections to the properlength and deliver them, substantially as and for the purposes setforth.

3. The mechanism for securing the section to the continuous strips whichcomprises an inclined hopper to receive and deliver the sections, thebottom of said hopper being arranged above the continuous binding-stripsfar enough to let the section pass freely under it, afeeder to push thesection forward between griping-rolls arranged to receive it, the saidgriping-rolls, and folders or binders arranged to turn the bindingstripsdown over the ends of the section, all combined substantially as setforth.

4. The combination, with the mechanism for formingthe sections comprisingthe paste-rolls,

hearing or griping rolls, the folder, and the compressing and cuttingroll, of the apron, which bears the sections from the cutting-roll tothe hopper, the said hopper, the feeder for pushing the sections forwardone by one between the griping-rolls, the said griping-rolls, and thefolders for turning the binding-strips down on the ends of the sections,arranged substantially as and for the purposes set forth.

5. The combination, with the steam-drum and the endless apron arrangedto encircle it, of the pasting-mechanism for pasting the binding andintermediate strips, the endless apron U, the hopper V, the rolls 1 l,the feeder m, the bearing-roll m, andithe folders W, all ararranged tooperate substantially as set forth.

6. The mechanism for folding the strips of lining or fabric as it comesfrom the machine, consisting of a pair of oscillating arms arranged ateach end of a folding-box and ad apted to rise and fall as the boxfills, said folding-arms having fingers at their extremities to takeinto the bight of the fabric and lay it, cams to take under thefolding-arm and withdraw the fingers at the end of the stroke of thearms, and forked holders, pivoted at the ends of the folding-box,between the foldingarms and the cams, and arranged to be pressed intothe bight of the fold by the folding-arms, so as to retain the fabricwhile the arms are making the succeeding fold, substantially as setforth.

7. The combination, to form a folding mechanism, of the slides 1 1,slotted end plates, 2 2, sliding-blocks 3, spindles 4., bosses 5, cranksor arms 6, the folding-arms 7, springs 8, cams 9, folding-fingers 10,counter weight or weights 15, and forked holders 16, provided withfingers 17, all combined and arranged to operate substantially as setforth.

8. An endless apron composed of metallic Vancanson chains, to which aresecured metallic slats to form the bed or apron proper, substantially asand for the purposes set forth.

9. The combination, with the paste and doctor rolls 9 and h and thehearing or idler roll j, of the twine-spool 70, all arranged to operatesubstantially as set forth.
